width would depend on wheel backspacing & if it's stock, mini tubbed or really tubbed.

I have a 9 in my 67 and its 1 inch each side narrower than stock.It was in the car when I bought it.Allows for a deeper rear wheel,which looks good.The down side it the brake backing plates are very close to the springs.Parking brake on some rear discs might pose a problem.

There are a few 9" rears that will go under a stock 1st or 2nd gen without being tubbed or the rear being narrowed. They can be found under the Early Broncos, Lincolin Versallies/Granadas, certain Mavericks have an 8" and I believe a 9" from an early Mustang is close as well.
The chart below shows most of the different manufaturers outside wheel mounting surface to opposite Outisde wheel mounting surface dimensions. You will have to deal with spring pad relocation as well. You can account for some differences in width by playing with the backspacing on your wheels

Hello charley

Yes the frame has been moved.The rails sit around 29&1/4 apart.And I still have a back seat.Also my 1/4 windows still go down about 90% ,Trunk lid still uses the stock rods/bars as well.

I did a 2" mini tub in my 65 and also moved the perches in the same amount. I bought a Moser 9" with the mono leaf perches on the housing and also had Ford bearing hubs with the 10/12 bolt bolt pattern so I could use my original backing plates. I did a LOT of measuring with wheels and tires, backing plates etc, and ordered it on a Monday. The rear, axels and bearings all ready on the axels were on my porch Wednesday. Popped it in and everything fit perfect. Can't say enough about Moser service. that was with a 15x8, 4 1/2 backspace Weld wheel with 5/8 studs. I have a 295/65-15 MT radial in the well and can slide my hand between the tire and body. Dave

I'd recommend 65 Post's route. I did the Versailles' 9inch route. It works but after all the money I put into it I wish I would have bought something new and made to fit from Moser or Currie. The pricing is hard to beat once you really add up what you have to put into it.
